Saudi Arabia, like many other developing countries, has had extensive experience with rapid urbanisation and infrastructure expansion, especially in the area of buildings. Buildings play an even bigger part, accounting for roughly 80% total national electricity consumption. Forecasts indicate that domestic energy consumption will rise at a rate 4% to 5% annually by 2030, based on current local ...

High-rise buildings in cold regions have a requirement of ecological improvement due to the continuous response climate change throughout year. This study evaluates wind environment, light thermal and energy consumption environment using Phoenics, Ecotect, DesignBuilder tools, utilizing high-rise residential building an intensely place as example. With goal repairing buildings, green energy-sav...

The purpose of energy-saving retrofit rural dwellings is to obtain a more comfortable indoor thermal environment with reasonable investment. utilization rate heating and air conditioning equipment for in poor areas very low, the buildings operate natural ventilation mode all year round. Since existing research on aimed at air-conditioned buildings, methods results are not applicable dwellings. ...

Recent advances in computing software have enabled the development of calibrated building energy simulations tools that allow retrofit-related analysis including optimization and energy-efficient design. However, to create a national climate plan, using these may imply great deal effort (time, cost, human resources) carry out for full set different types, construction, geometries, design parame...

Starting from the second half of 2022, energy market, in particular, European natural gas supply, passed through an eventful period. The sanctions imposed on Russia because Ukrainian war rearranged steadiness suppliers to continent, and major concerns arose regarding reduction primary consumption, particularly for heating cooling purposes. This study proposes a method mapping loads building as ...

In hot arid climates, air conditioning in the summer dominates energy use buildings. Kuwait, demand buildings is dominated by cooling, which also determines national peak electricity demand. Schools contribute significantly to cooling demand, but suffer from poor ventilation. This paper presents analysis of a ventilation and system for school classrooms using wind catcher natural evaporative co...

Buildings and the construction sector account substantially for global energy consumption. In hot-humid areas of China, suboptimal thermal comfort in classrooms has heightened their cooling load It is necessary to renovate buildings outdated code according current weather conditions save energy. This study thus aimed examine effects such designs on load, based an actual classroom building durin...

Old buildings over 20 years after completion account for 58.2% of all in Korea. Moreover, built 30 ago with weak insulation levels have a significant impact on energy consumption the building sector. Therefore, improving performance existing is critical. In addition, green remodeling old public currently being implemented accordance mandatory zero-energy construction policy. Korea, ECO2 based I...

Semi-transparent photovoltaic (STPV) windows, one of the building façade elements, can generate electricity and provide a certain amount daylight for occupants. Nevertheless, expensive cost unsatisfying indoor performance in room are common problems with STPV windows. This study investigates thermal, daylight, energy, life-cycle windows by considering varied window-to-wall ratios, orientations,...

daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. window configuration significantly affects the intensity and uniformity of daylight. this paper aims to investigate the effect of wind...
